Chapter 4: Statistical Analysis and Hypothesis Testing

4.7 Survey Analysis

The following analysis has been conducted over a survey that was answered by the whole staff of the company. The sample consisted of the developers who constitute the developing task force of the organization. A thorough analysis will be performed on the following chapters; the goal of this chapter is to show the results of the survey and to provide a simple summary of the responses.

Question 1: How do you estimate your understanding of Agile Methodologies?

Figure 4.7: Histogram of Q1 versus count of answers

A first analysis of these results indicates that they are actually following the right way of writing the code. Through this question indicate understanding of agile process by employees

51

in this company. The figure shown upper average range is more than 50 percent of employees.

Question 2: How do you estimate your understanding of Agile Methodologies?

Figure 4.8: Histogram of Q2 versus count of answers

There is mention that indicates knowledge of employees by their work experiences in agile process in software development. This figure show that more than 50 percent of employees have over 3 years’ experience in this filed.

Question 3: Has adoption of management commitment in organization dimension of agile process effect delivering a good working product?

Figure 4.9: Histogram of Q3 versus count of answers

There are two approaches for answering this question. The first one says that testing should distinguish management commitment in organization and effect of agile process in quality. This leads to two ideas, that a person testing a code that is not his/her can find goals in relation of organization and quality. Therefore, we see that there is significant part of the developers who are being supported for the testing phase, something that Lean states not to be adequate.

Question 4: Has agile logistical arrangements in organization dimension of agile process effect delivering a good working product?

Figure 4.10: Histogram of Q4 versus count of answers

In this question we believe that it can make relation between organization factor and quality of products. This question will estimate success or failure of first hypothesis which indicate in previous chapter.

Question 5: Has management commitment in organization dimension of agile process effect total estimated cost and effort?

Figure 4.11: Histogram of Q5 versus count of answers

This question clearly states that the relation between organization in agile process and total cost of projects.

53

Figure 4.12: Histogram of Q6 versus count of answers

From these answers this is an obvious fact that developers as employee estimate effectiveness of delivering on time of projects.

Question 7: Has customer relationship in people dimension of agile process effect delivering on time?

Figure 4.13: Histogram of Q7 versus count of answers

It is therefore very important that customer relationship for making customization effect delivering. As mentioned in figure more employees estimated that customization reduces delivering of time and will reach better time schedule that traditional work.

Question 8: Has customer relationship in people dimension of agile process effect total estimated cost and effort?

54

Figure 4.14: Histogram of Q8 versus count of answers

With this question we aim to measure the cost of the released products, if they spend a lot of cost in fixing bugs it means that there is not enough quality during the development process. On the contrary, the answers show that they are not having many difficulties to achieve projects with high quality since they don’t spend a significant amount of time in fixing problems and bugs. This might be due to the fact that the majority of the products that have been already released are not very complex and, therefore, they are less likely to have a high rate of bugs or problems.

Question 9: Has necessary skill-set in people dimension of agile process effect total estimated cost and effort?

Figure 4.15: Histogram of Q9 versus count of answers

One of the key thing is skill-set says about assigning tasks is that this should be done by the developers; each of them should be able to choose what they want to do in total cost.

Question 10: Has progress tracking mechanism in process dimension of agile process effect delivering a good working product?

55

Figure 4.16: Histogram of Q10 versus count of answers

By this question, we are trying to analyze progress tracking mechanism and quality of product. By this question we are going to find tracking in process factor will effect quality of product which shows in figure it will not much effective.

Question 11: Has progress tracking mechanism in process dimension of agile process effect delivering a good working product?

Figure 4.17: Histogram of Q11 versus count of answers

This is similar to question 10 which the difference relies in that further improvement can mean delivering of good products.

Question 12: Has customer presence in process dimension of agile process effect total estimated cost and effort?

56

Figure 4.18: Histogram of Q12 versus count of answers

The goal of the question is to analyze the customer presence effect total cost in delivering software on time, to see if they realize about how often employee do so.

Question 13: Has completion set of correct agile practices in technical dimension of agile process effect delivering a good working product?

Figure 4.19: Histogram of Q13 versus count of answers

More than an analysis question, this question helped us to know the technical dimension of work inside the organization to reach quality of production.

Question 14: Have technology and tools in technical dimension of agile process effect total estimated cost and effort?

Figure 4.20: Histogram of Q14 versus count of answers

A first analysis of these results indicates that they not only usually achieve cost estimations; it also means that they seem to be confident about their skills technology and tools in cost estimating.

Question 15: Have multiple independent teams in project dimension of agile process effect meeting all requirements by the customer?

57

Figure 4.21: Histogram of Q15 versus count of answers

This question is used to measure the amount of time they spend in multiple independent teams planning and doing follow up by scopes.

Question 16: Have life-critical and schedule in project dimension of agile process effect meeting all requirements by the customer?

Figure 4.22: Histogram of Q16 versus count of answers

Question 17: Have life-critical in project dimension of agile process effect total estimated cost and effort?

58

Question 18: Have risk analysis in project dimension of agile process effect total estimated cost and effort?

Figure 4.24: Histogram of Q18 versus count of answers

The last question of the survey is designed to measure the size of all currently ongoing projects. With this information we will be able to better analyze the management side of the organization.
